CONCRETE FLOOR AND COLUlVIN CONSTRUCTION.

u Appucation inea July 25, 190e, serial No. 327,721.

To a?! ruimen z'zf may concern.' i i Be it known that we, Evnnnr'r A. Dumme, of Minneapolis, and CLARENCE E. PRINCE, of Excelsior, Hennepin county, Minnesota, have invented certain new and useful Improvements in Concrete Floor and Column Construction, of which the following is a speci ication.

Our invention relates toa reinforcedcon`- crete construction; and the object of the invention is to provide a floor and columns whereon the strain or weight ofthe load will be uniformly distributed and equalized.`

A further object isto provide a floor and column construction;wherein (aside from the upright columns), all depending or projecting supports, such as girders, which present an unsightly appearance and take up storage space andshut-out light, are entirely eliminated.

A further object is to provide `a reinforced concrete construction which will be comparatively simple and economical to erect, but very strong and capable of supporting a heavy load. l H i Ourinvention consists in the several features hereinafter particularly described and then sought to be l clearly delined bythe claims; i

In the accompanying part ofthis specification, i

F igure 1 is a sectional view illustrating the floor and columns, one of said columns being shown in vertical section to illustrate thel reinforcing rods embedded therein.

form or mold in which the column is built up..`

p Fig. 8 is of Fig. 5. i.

a sectional view on the line y/-y/ represents the outer wall of the building' shown in this case as composed ofbrick, and Slis a footing ar ranged beneath the floor el and the supportmg `columns above. In erecting these col* umns a sleeve or collar 5 preferably of meta-l is provided upon the door 4l directly above the footing 3. A ring 6 having a series of perforations Tis placed upon the top of the sleeve 5` and aform 8 also composed of metal sections separably secured together by? means of flanges 9 and bolts l0, is placed upon the sleeve 5 inclosing the ring 6. Rods 11 are thrust through the holes in the ring 6 into the spaceinclosed by the sleeve 5, and the interior of the sleeve and form is Filled with concrete with the rods embedded therein and entirely concealed from view. Aseoond ring corresponding to the ring 6 is provided near the middle of the column and another one at the top. The rods extend vertically through these rings and after passing through the upper one are turned down substantially at right angles to a horizontal position and embedded in the floor panel 12, and extended to theremote end thereof, the rodsbeing bent so that they will be near the under surface of the panels vat the middle thereof and near theupper surface at the ends as shown in Fig. 1, thereby providing a truss effect and forming a substantial brace or reinforcement for the horizontal floor. The ends 13 of the rods are turned either up or/down to anchor them more securely. Some of the rods will have their horizontal ends turned up and embedded in the base of the column above and others will be turneddown and embedded in the top of the column` beneath. `Both columns are thus locked securely and held against lateral or spreading movement. he rings arranged at `interv-als and through which the vertical portions: of the rods pass will hold them in proper relation with one another and prevent any possibility of the strain on one rod from pulling it out of its proper position with respect to the other rods and the column in which they are embedded. A cap 111 is vformed at the top of each column within a form 15 and the vertical and hori- Zontal portions of the rods are preferably unitedacross the angles at the top of the columns by means of loops 16 which are embedded `in the caps and serve to brace and strengthen the top of the column and .form an additional support for the floor panels at this point. The forms 8 and 15 are removable from each column after its completion and may be utilized in the erection of anotherl column. For the purpose of holding the vertical portions of the rods in proper relation with one another -we prefer toprovide coils 17 of a suitable gage of wire having their ends attached to the middle and top and bottom rings and wrapped around the upright portions of the rods to yhold them from spreading during the erection ofy the column. Suitable wooden false work indicated by numeral 18 will be employed in connection with the columns and will be removed as soon as the concrete has properly set.y Rods 19 forming a portion of a netting may also be used.

The truss rods as shown in thedrawing, all start at the bottom of the columns and pass out atthe top substantiallyT at right angles and cross to the next column, the ends of the horizontal portion being bent and anchored either in the iioor or in the base of the column next above or down into the column below. The rods are alternately arranged, that is, one rod starts at the base of one column and extends vertically therethrough and horizontally7 to the next column and the adjoining rod -starts in the last named column and terminates at the top of the first named one. That is to say, in the embodiment of the invention, as shown in the drawing, adjacent columns are connected by pairs of rods, the elements of each pair having their vertical portions in diiferent columns and being arranged to alternate with the elements of the other pair. At intervals around the column, the rods instead of extending straight across the floor `panel to the opposite column, are run diagonally through the panel to the column on the opposite corner. `The floor space is thus divided by the radiating rods into comparatively small triangular sections of uniform size and whereon the load, by the arrangementof the rods described, is equally and uniformly distributed,`and we-are able to avoid massing of the rods about the columns and the consequent waste of material.

A construction of this kind is not only economical and comparatively simple to erect, but it forms a very substantial structure in which: no space is `unnecessarily occupied'by supports, and which is capable, owing to the equalization of the strain,of

sustaining a very heavy load. The molds or forms for the vertical columns may of course, be varied in shape and size to pro duce the desired configurations of the columns.

We claim asour invention:V f f i 1. A concrete ioor'andcolumnfconstruction comprising upright concrete columnsV and connecting" floor panels betweenllthem, and reinforcing rods in the columns and the panels, each rod being in one continuous piece and extending from the base ofone column upwardly to the top thereof and thence bent laterally andextending through the panel as far as another column or wall and at such column or wall bent `into aline ment therewith, thus locking the columns one to the other by rods anchored at 'its opw posite ends in separate columns-or walls, substantially as described.
